Official summary
Some 2020-2022 Explorer/Aviator/Police Interceptor Utility vehicles equipped with a hybrid powertrain may exhibit an illuminated MIL with diagnostic trouble code (DTC) P2D40. This may be due to the chiller not interpreting the correct cooling value of the high voltage battery chiller. To correct the condition, follow the Service Procedure to diagnose the cause of the incorrect value.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
